Answer:
2022 L
Explanation:
Ideal gas laws will work for gas in the balloon
The general gas law is for a gas at two arbitrary states 1 and 2 is given by
(P₁ V₁)/T₁ = (P₂ V₂)/T₂
P₁ = 1.17 atm
V₁ = 200.0 L
T₁ = 20°C = 293.15 K
P₂ = 63 mmHg = 0.0829 atm
V₂ = ?
T₂ = 210 K
(1.17 × 200)/293.15 = (0.0829 × V₂)/210
V₂ = (210 × 1.17 × 200)/(293.15 × 0.0829)
V₂ = 2022 L
Ok they are both can formed by the same high pressure system . the heat waves are extended periods of above-normal temperatures . but the cold wave is an extended periods of below normal temperatures
